Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fully automatic bread maker that can produce freshly baked bread at a desired time simply by adding predetermined ingredients.

Conventional technology When making bread at home, equipment such as a kneading machine, fermenter, rolling pin, and oven are generally used, but it is very difficult to control the temperature and time, and it is difficult to make bread regardless of the season. 1. It required a great deal of skill to make delicious, freshly baked bread with a good shape. In order to solve these problems, as shown in FIG. 4, various devices have been proposed that can automatically bake bread simply by setting the time. In this configuration, a firing chamber 6 equipped with a motor 3, a lower heater 4, and a heat insulating material 5 on the outer periphery is fixed to a chassis 2 provided in a main body case 1.
A rectangular parallelepiped bread mold 8 having kneading blades 7 is installed in the baking chamber 6, and is driven at a reduced speed by a belt 9 and pulleys 10°11. Further, above the firing chamber 6, an upper heater 12 and an inner M
13 is connected to the lid body 14 so as to be openable and closable.
A water tank 15 and a solenoid I7 for opening and closing the water tank water inlet 16 to supply water into the bread mold 8 are installed. A control section 18 controls the motor 3, heaters 4 and 12, solenoid 17, and the like. With this configuration, when ingredients are put into the bread mold 8 and the baking time is set, operation starts at a predetermined time, water is supplied to the bread mold 8, and bread dough kneading begins with the rotation of the kneading blades 7. Bread is baked through the process of fermentation, degassing, shaping, fermentation, and baking.

Problems to be Solved by the Invention In such a conventional configuration, in order to make well-shaped square bread, the baking mold is a rectangular parallelepiped container, and the cross-sectional shape when viewed from above is rectangular. For this reason, when kneading bread dough, the flour in the corners often remains until the end. In particular, in the case of a rectangular cross section, if the rotating direction of the kneading blades 7 is clockwise as shown in FIGS. 5 and 6, the dough will be (A), (
The resistance is large at the corner of C) and it is easy to stop, and conversely (
B) and (D) corners are difficult for bread dough to stay in place, making it difficult for bread dough to be mixed with flour, and (B).

There is a lot of powder left in the corner of (D). For this reason, the number of rotations of the kneading blades 7 may be increased to swing the bread dough with a large centrifugal force to mix in the flour from the corners. This is a problem for devices that operate automatically during the night.

An object of the present invention is to provide a fully automatic bread making machine that produces low operating noise and can achieve good kneading without leaving any flour residue.

Means for Solving the Problems The fully automatic bread making machine of the present invention includes a baking chamber having a heater;
A rectangular parallelepiped bread baking mold that can be detachably installed in the baking chamber, and a kneading blade driven by a motor are provided at the inner bottom of the bread baking mold, and the motor is rotated in forward and reverse directions to change the direction of rotation of the kneading blade when kneading bread dough. It is characterized by having a means.

Function: According to this configuration, the rotating direction of the kneading blades changes, so even if the cross section is a rectangular bread baking mold, when rotating in the forward direction, the dough will mix in the flour from one diagonal corner; When rotating, the flour from the other diagonal corner is mixed into the bread dough, and even when rotating at low speed, all the flour is kneaded and there is no remaining flour.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 shows the entire fully automatic bread making machine of the present invention.

A motor 22 is fixed to a chassis 21 provided within the main body 20. A motor cooling fan 23 is fixed to one end of the shaft of the motor 22, a small pulley 24 is fixed to the other end, and power is transmitted to the bell 1 via 25 to a large pulley 26. Furthermore, the chassis 21 has a lower heater 2.
A firing chamber 30 is provided with a heat insulating material 28 on the outer periphery and is fixed via a pulley bearing stand 40. Inside this firing chamber 30, there is a kneading blade 3 that can be attached and detached at the inner bottom.
There is a rectangular parallelepiped bread baking mold 31 with a blade shaft 34. The upper connector 37 is pivotally supported. More bread baking mold 3
1 is a pulley bearing stand 40 fixed to the chassis 21 and pivotally supporting the large pulley 26, pulley shaft 39, and lower connector 38;
and are removably fitted. Furthermore, an elastically supported temperature sensing portion 49 protrudes from the side surface of the baking chamber 30 and is in pressure contact with the side surface of the bread baking mold 31 . Firing room 30"
An L heater 41 is arranged almost all around the inside of the second part. The upper surface of the firing chamber 30 includes a lid 42 that can be opened and closed, a mounting shaft 44 protruding from the center of the lower surface of the lid 42, a presser spring 45, and a presser plate 46.
There is an inner lid 43 elastically supported by the lid body 4.
2, the lower surface of the outer periphery of the inner lid 43 becomes the upper heater 4.
1. It is designed to come into pressure contact with the top surface. The lid 42 is provided with an opening knob 47 and a latch 48 for opening the lid 42. A pin shaft 56 is provided on the small pulley 24 side of the motor shaft at a position slightly eccentric to the motor axis, and a reciprocating pump 54 configured to vibrate an elastic membrane plate made of rubber or the like is attached to the side surface of the chassis 21.

A pump-side pin shaft 57 is fixed to the top of the elastic membrane plate,
It is connected by a pin shaft 56 and a connecting rod 55. A discharge pipe 53 of the reciprocating pump 54 communicates with a water tank 52 attached to the main body 20, and a water supply pipe 51 connects to the firing chamber 3.
It communicates with a water supply port 50 that is open so that water can be sprayed into the bread baking mold 31 inside the pan. 61 is a switch panel for inputting settings such as baking time.

62 is a motor 22. Lower heater 27, upper heater 4
This is a control device for determining and outputting control conditions such as 1. 60 is a back plate, and 59 is a leg rubber.

A bread baking mold 31 and kneading blades 32 are set in the baking chamber 30, and ingredients such as flour are charged. Close the lid 42, fill the water tank 52 with a predetermined amount of water, and close the cap (not shown) to seal it. In this state, the baking time of the bread is input from the switch panel 61, and when the predetermined time comes, the motor 22 starts operating and kneading is performed. At this time, at the same time, a pin shaft 56 provided eccentrically from the motor shaft center on the small pulley 24 on the motor shaft side rotates. Then, the pump side pin t is
The III 57 reciprocates and sends air pressure to the water tank 52 by vibrating the reciprocating pump 54. The water is supplied from the water tank 52 through the water supply pipe 51 into the baking mold 31, and is kneaded with ingredients such as flour by the kneading blades 32. . Then, the control device 6 controls the rotation direction of the motor 22 to be forward or reverse for a certain predetermined period of time, and kneading is performed for a while. Stop operation. Further, each step of next fermentation, degassing, shaping fermentation, and baking is performed automatically, and the bread is baked at the set time.

Since the kneading blades 32 are operated in reverse at predetermined intervals, even if the cross section of the bread baking mold 31 is rectangular, when rotating in the forward direction (clockwise) as shown in FIGS. ), the dough being kneaded tends to stay in the corner of (C) due to the resistance of the side wall of the baking mold 31, and at that time, the flour from that corner gets mixed in, and when the dough is rotated in the opposite direction (counterclockwise), On the other hand, since the flour from the corners of parts (B) and (D) is mixed in, almost no flour remains in the baking mold 31. In addition, there is no need to increase the rotational speed of the cross-conductor as in the conventional example, the noise is quiet, there is no scattering of flour, and it is possible to bake well-shaped bread.

As described in the detailed description of the invention, the fully automatic bread maker of the present invention is equipped with a control means for rotating the kneading blade drive motor in forward and reverse directions when kneading bread dough, so that the rotating direction of the kneading blade changes and the cross section changes. Even with a rectangular bread pan, when rotating in the forward direction, the flour from one diagonal corner will be mixed into the bread dough, and when rotating in the opposite direction, the flour from the other diagonal corner will be mixed into the bread dough. Even when rotating at low speed, all the powder is mixed in.
In addition to eliminating leftover flour, low-speed rotation reduces noise and eliminates scattering of flour, making it possible to bake well-shaped bread.
